An Innovative Approach of Economic Smart Aquaponics System

Aquaponics is a sustainable method of food production that combines aquaculture and hydroponics to cultivate fish and plants in a symbiotic environment. This paper presents the development of an IoT-based smart aquaponics system aimed at automating and monitoring key environmental parameters to optimize plant and fish health. The system is powered by a NodeMCU microcontroller, which integrates various sensors including a DHT11 sensor for temperature and humidity measurement, and a water level sensor to monitor the plant bed's hydration. A self-operating pump system manages the transfer of nutrient-enriched water from the fish tank to the plant bed, triggered by live data collected from the sensors. The collected data is transmitted via Wi-Fi to the Ubidots IoT platform, enabling live monitoring through a cloud-based dashboard. This approach not only reduces manual intervention but also enhances resource efficiency and promotes sustainable urban farming. The system demonstrates a practical and scalable solution for smart agriculture, making it suitable for both research and realworld applications. This system is designed to reduce the need for manual effort by automating key functions involved in aquaponics management. By streamlining routine tasks such as water circulation and environmental monitoring, the setup helps improve efficiency and reliability. Moreover, it promotes sustainable farming by making use of affordable, easy-to-deploy hardware components. The project illustrates how practical and cost-effective technology can support smarter, greener agricultural methods suitable for both small-scale and larger operations.
